IMPROVEMENT IN LUBRICATORS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No. 129,360, dated July 16,1872.

To all whom it may concern:

Be it known that I, MATTHEW MORTON, of Romeo, in the county of Macomband in the State of Michigan, have invented certain new and usefulImprovements in Steam-Cylinder Lubricator; and do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangementof a steami cylinder lubricator77 for using tallow, lard, or

other article that will congeal, said lubricator comprising a heater` orreservoir and a lubricator proper, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a side elevation, and Fig. 2 a longitudinal verticalsection, of my lubricator. Fig. 3 is a plan view of the heater orreservoir. Fig. 4. is a side view of the lever by which the lubricatoris operated 5 and Fig. 5 is a cross-section of the lower part of thelubricator.

A represents the cover for the steam-chest, in which is screwed orotherwise secured the bowl B. Through this bowl passes the plug C, andon top of the bowl is screwed or otherwise secured the reservoir D. Theplug C is slightly tapering, as shown in Fig. 2, and is cylindrical,with both ends closed, having only two openings, as will be hereinafterdescribed. From the smaller end of the plug projects a screw, H, whichpasses through a spring-brace, I, and is fastened by a nut, J, the saidspringbrace being in the form of a cross with the ends or arms bentinward and bearing against the side of the bowl B. From the bowl B apassage, a, leads to the steam-chest, and two other passages, b d,connect with the reservoir D. The passage bleads into an upright pipe,E, within the reservoir, while the passage d communicates direct withthe bottom of the reservoir. The plug C is a hollow shell, forming theoil or tallow-chamber, and is provided with two openings, b d',corresponding with the passages b d of the bowl B. The various passagesand openings are so arranged that when the plug is turned one-halfaround the opening d will be opposite to and against the passage a, soas to open communication from the plug to the steam-chest. G representsthe lever with which the plug Gis turned, said lever being in the formof a cross, as shown in Fig. 4.. The parts should be so arranged thatwhen the lever is turned to one side, and one ofthe cross-arms restsupon the cover A, the openings b' d are against the passages b d,allowing the melted lubricating material from the bottom of thereservoir D to pass through d d' into the plug or chamber C, while anysteam or air that may be in said plug passes through b b and pipe E intothe top of thereservoir. By turning the lever G one-fourth of arevolution, so that it stands upright, all the passages will be closed;and by turning the 1ever still another one-fourth of a revolution, sothat the other cross-arm rests upon the cover A, the opening df comesagainst the passage a. and allows the lubricating material to pass outof the plugor chamber() to the chest and cylinder. The heat iscommunicated through lthe bowl to the reservoir, whereby the tallow,

lard, or other material becomes melted and it for use without trouble,instead of having, as heretofore, to melt such material in a separatedish. Thus the reservoir may be lilled with hard tallow, lard, or anychilled oil. It is, in fact, a reservoir and heater holding enough tolast about two days without further trouble. It will also be noticedthat the entire pressure of the steam is inthe inside of the plug C,having no communication with the outside to cause friction, sticking, orwear. Thus, if the pressure of the spring-brace I against the bowlshould only be one pound, it will still hold the plug in against thepressure of steam, even if that was three hundred pounds. It is,therefore, anti-friction against the pressure of steam, and the wear ofthe plug, if there is any, is toward said spring-brace, which thus makesthe plug self-adjusting, giving the plug no chance to stick, or becomeloose and leak.

It will be seen that the reservoir D is connected to the bowl B by amale screw on the bowl and a female screw in the bottom of thereservoir, so that the reservoir may at any oriices a b d, plug C withorifices b d', screw H, brace I, and nut J with the detachable reservoirD and tube E, all constructed to operate substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of February, 1872.

l' MATTHEW MORTON.
